Once regarded as Poldervaartite, this mineral was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This was found around 2000 from a substantial pocket, purchased by Charlie Key. This fine example shows crystals of Olmiite with two different colors; one a milky beige, and the other a more transparent salmon color. It's in great condition. It has a glassy, bright surface. It comes mounted on a 1.25 inch/ 3 cm acrylic base. Data last checked on 12th Sep 2025 - specimen may no longer be available
